Assessing the accuracy and robustness of a process-based model for coffee agroforestry systems in Central America
(Springer, Nueva York (Estados Unidos), 2020)
Coffee is often grown in production systems associated with shade trees that provide different ecosystem services. Management, weather and soil conditions are spatially variable production factors. CAF2007 is a dynamic ...
Global transpiration data from sap flow measurements: the SAPFLUXNET database
(2020)
Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy and carbon budgets at the land-atmosphere interface. However, despite being the main land evaporative ...
Unraveling Ecophysiological Mechanisms in Potatoes under Different Irrigation Methods: A Preliminary Field Evaluation
(2020)
Potatoes—a global food security and staple crop—is threatened by dry spells in drought-prone areas. The use of physiological thresholds to save water while maintaining a reasonable tuber yield has been proposed, but their ...
Forecast models of coffee leaf rust symptoms and signs based on identified microclimatic combinations in coffee-based agroforestry systems in Costa Rica
(2020)
Coffee leaf rust is a polycyclic disease that causes severe epidemics impacting yield over several years. For this reason, since the 1960s, more than 20 models have been developed to predict different indicators of the ...
Development of an Open-Source Thermal Image Processing Software for Improving Irrigation Management in Potato Crops (Solanum tuberosum L.)
(2020)
Accurate determination of plant water status is mandatory to optimize irrigation scheduling
and thus maximize yield. Infrared thermography (IRT) can be used as a proxy for detecting
stomatal closure as a measure of plant ...
Region-specific emission factors for Brazil increase the estimate of nitrous oxide emissions from nitrogen fertiliser application by 21%
(Elsevier, Ámsterdam, Países Bajos, 2020)
The use of synthetic nitrogen fertilisers is one of the most important land management practices proposed to improve crop and pasture productivity. The use of such fertilisers in excess can lead to greenhouse gas (GHG) ...
Economic constraints as drivers of coffee rust epidemics in Nicaragua
(Elsevier, Ámsterdam, Países Bajos, 2020-10)
Coffee rust (Hemileia vastatrix) epidemics of an intensity never seen before have hit Central America since 2012. This study set out to identify management and socio-economic factors that facilitate coffee rust development ...
Policy Note: Policy Responses to Ensure Access to Water and Sanitation Services During COVID-19: Snapshots from the Environment for Development (EfD) Network
(2020)
This policy note provides a snapshot of water and sanitation measures implemented by governments in response to the COVID-19 pandemic in 14 countries in the Global South: Costa Rica, El Salvador, Guatemala, Honduras, ...
CGIAR modeling approaches for resource-constrained scenarios: I. Accelerating crop breeding for a changing climate
(American Society of Agronomy, 2020)
Crop improvement efforts aiming at increasing crop production (quantity, quality) and adapting to climate change have been subject of active research over the past years. But, the question remains ‘to what extent can ...
Accurate Differentiation of Green Beans of Arabica and Robusta Coffee Using Nanofluidic Array of Single Nucleotide Polymorphism (SNP) Markers
(2020)
Green (unroasted) coffee is one of the most traded agricultural commodities in the world. The Arabica (Coffea arabica L.) and
Robusta (Coffea canephora Pierre ex A. Froehner) species are the two main types of coffees for ...
